What we are not saying: Apple reads your iMessages.
What we are saying: Apple can read your iMessages if they choose to, or if they are required to do so by a government order.

As Apple claims, there is end-to-end encryption. The weakness is in the
key infrastructure as it is controlled by Apple: they can change a key
anytime they want, thus read the content of our iMessages.

Also remember that the content of the message is one thing, but the
metadata are also sensitive. And there, you rely on Apple to carry your
messages, thus they have your metadata.
